During the first half of 1925 work began on the overground section of the Ferrocarril Metropolitano de Barcelona began. It is in this section, adjoining Riera Blanca, where the origin of the line was located along with the office and depot building.

The first inhabitants of the depot were the well-known class 100 carriages. Measuring 21.9 metres long, 3.296 metres wide, 4.3 metres high, and a capacity of 330 passengers, these were the largest metro carriages in the world until they were surpassed by the Toronto Metro in 1961.

The Class 100 carriages were retired in 1979 after 53 years of service.

Bordeta station opened on 10 june 1926 and had just oneplatform wich was 50 meters long (extended to 70 metres on 1957) and, covered by a metal canopy. It had one entrance from Riera Blanca. It was not until 1932 that a second platform was built with Its own entrance, when the line was extended to Santa Eulàlia station, kown at that time as Bordeta-Cocheras.

Bordeta maintained this layout until its closure on 23 december 1983, when the new underground Santa Eulàlia station was opened. Since then Bordeta station is only used by the driving personnel to take charge of trains leaving the depot, or by passengers needing to change train if the one they are travelling on is going to be taken out of service.
